I did some checking.  There are some things allowed, but they are limited:
Light Goose Conservation Order -- 02/07/2017 - 04/30/2017 
Hours: One-half hour before sunrise to one-half hour after sunset 
Notes: Hunting is limited to snow geese, blue geese, and Ross's geese.

Spring Turkey Hunting, Youth (ages 6-15) -- 04/08/2017 - 04/09/2017
Hours: One-half hour before sunrise to sunset
Notes: Youth hunters who are age 6-15 on opening day may hunt.

If s/he doesn't appear to be a youth shooting at turkeys or an adult shooting at snow geese, find their vehicle, take a picture of the plates, and report it to the EBCA headquarters.  They have MDC personnel there.

Cheers and good birding,
